Answer 1

This one helped me:

 if defined?(WillPaginate)
   ActiveSupport.on_load :active_record do
     module WillPaginate
       module ActiveRecord
         module RelationMethods
           def per(value = nil) per_page(value) end
           def total_count() count end
         end
       end
       module CollectionMethods
         alias_method :num_pages, :total_pages
       end
     end
   end
 end
